LOG-LOADER.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed December 28,1906. Serial No. 349,832.

To all whom it may concern:

Be it known that I, JonNR. MeGrFrEn'r, a citizen of the United States, and a resident of Duluth, county of St. Louis, and State of Minnesota, have invented a new and useful Improvement in Log-Loaders, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

My invention, relating, as indicated, to improvements in loading devices, has as its more immediate object the provision of a readily transportable log-loading machine. To this end it is concerned not so much with the character of the machine itself aswith the means devised for loading the same onto a vehicle in order to permit of its ready removal from one place to another, as may be demanded by the exigencies of the use for which it is intended.

Said invention, then, consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 represents in side elevation one of the several types of loading machines employed in loading logs onto cars, together with a truck or car in combination with which such loader is designed to be operated; Fig. 2 is an end elevation of such loader and car; while Fig. 3 includes respectively a plan view and side elevation of removable ways or rail-sections designed to be employed, in the manner hereinafter fully set forth, in effecting the elevation of the loader onto such car when it is desired to prepare the former for transportation.

The type of loading mechanism chosen for the purpose of illustration in connection with my present invention comprises in the main simply a rectangular frame adapted to straddle a railway track and permit the passage therethrough over such track of the ordinary flat cars employed in logging operations, such frame being provided with an upper deck whereon is supported the usual hoisting mechanism and the like for performing the operation of loading, forwhich the device is primarily intended. The construction of such loading 'm echanism being generally understood all parts thereof are here omitted save the winding drums for operating the several cables.

Having reference, then, to Figs. 1 and 2, it will be noted that A designates the upper platform or deck of the loader frame, which platform is supported upon four bow-like legs A located near its respective corners. These legs are connected by lower longitudinal bars, preferably channels, as shown, and the frame is otherwise braced, in order to stiffen it against the shocks to which it is apt to be subjected in use, in any approved fashion. Journaled in suitable boxes 0. on the under side of the platform, near the respective ends of the frame, are two cross shafts B B, on the ends of which are secured double flanged wheels b 12. These flanged wheels exrend downwardly a few inches below the lowermost part of the frame deck. Near one end of the platform or deck, the left one as shown in Fig 1, is secured a spotting sheave C, while near the other end of such deck is secured a block 0. A spotting cable or line C from one of the drums c of the hoisting mechanism may be run over spotting sheave 0 alone, or over such sheave and block G at the other end of the frame, as desired, or around such sheave and the block O at the other end of the frame.

In its normal position when in use for loading logs or the like onto cars, this machine straddles the track, as has been stated, the legs b'eing bent inwardly, and resting upon shoes which are supported by the ties of the track. The empty flat or logging cars can then be successively shoved or drawn between such legs and underneath the deck, the double flanged wheels b being raised a sufficient distance to amply clear the decks of such cars. When the machine is to be moved, the loading frame or machine is elevated bodily on one of the cars in question in the following manner: Secof timbers D so as to slope downwardly at each end. These rail sections or ways are then placed longitudinally on one of the flat cars so as to be in position to engage the aforesaid flanged wheels I) when. the car is drawn underneath the frame. The central and major portions of the respective rails D, which obviously lie parallel with the car deck, are sufficiently elevated by the timbers D upon which such sections are mounted to raise the loader-frame legs entirely off the ground or ties upon which their feet normally rest, when engagement is had with the flanged wheels I). In order to thus draw the car through beneath the frame, and thereby elevate the latter thereon, the spotting line or cable 0 already described is conveniently utilized. If the car upon which it is desired to load the frame stands behind the machine, that is, to the right as illustrated in Fig. 1, such spotting line is run over spotting sheave C only, its free end being connected with the rear draw-head of the car. Obviously, upon winding in the line, the car will then be pulled forwardly underneath the frame with the result, as regards the elevation of the latter, previously noted. When, on the contrary, the car which it is desired to utilize in the manner described, stands in front of the machine, the spotting line C is passed both over sheave C and block C, and then forward to the other cross-head of the car. In Fig. 1, the cable 0 which is represented by a broken tions of rail D, Fig. 3, are mounted on the upper faces line, is shown in both of these alternative positions. Suitable retaining means (not shown) are of course employed to prevent the frame from running off the ways or rail-sections when the car is put under motion.

The car illustrated in the drawings as being utilized to thus transport the loading machine, is an ordinary fiat or logging car, as has been stated, upon which the ways or rail-sections D are only temporarily laid when it is desired to load the machine thereon. Obviously, however, a special car may, if desired, be provided upon which corresponding rail-sections are perma nently secured, and which may be provided furthermore with self-propelling mechanism, the method of loading the machine thereon being otherwise identical with that described. Where a special car is thus employed, it may be run backwardly along the track and stand at the rear of the cars to be loaded, or such other disposition as may be feasible may be made of it instead. It is to the means which I employ for jacking up or elevating the machine frame upon the transporting car, whatever the character of the latter, that I would here invite attention. My device is offered as being particularly a practical one for use in connection with heavy loading machines which are not required to be automobile, and ordinarily it is contemplated that the use of the removable ways or track sections will be favored, for these can be carried along on the machine when not in use, and any ordinary car, by means thereof, can be converted on short notice into a suitable truck for receiving the frame and transporting where it is desired.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by the following claims or the equivalent of such stated means he employed.

I therefore particularly point out and distinctly claim as my invention 1.
